Pretty slick the way they disguised the speaker with the dial, eh?  
oOo!
That may be the coolest looking dial illumination ever seen on an AA5. And this isn't any kind of camera exposure trick, it really looks like that.
aAa!
I dunno, this may represent some manner of cutting edge technology in optics for its time.  All that light is coming from one dinky little #47 bulb, which is just under 1 watt.

Restoration notes:

The successful completion of this project represented a triumph on several levels.  I had been tinkering with this set way back in my early teens and never achieved so much as a flicker from the tube filaments, it was dead.  When I finally took it on again in 2005, although I had several radio fixes under my belt, it still proved to be a challenge, one that altered one of my previous practices in technique. 

While I admire those old radio repair craftsmen who can weild a soldering iron with such surgical skill that they leave nary a trace of their presence . . . I'm not one of them.  Or, as Doug Houston told me, "You don't have the touch!"  No, I don't, and I broke not one, but two of the wafer sockets in this set proving it.  From that point on I adopted the "loop" or "hook" method, whereby the old capacitor or resistor is cut out at its body, leaving the leads in place.  Fashion a hook at the end of the old lead, loop the new component lead around it, crimp, and solder.  Unless one plans to mount their chassis in a glass case with the underside facing out, this technique has nothing but advantages going for it compared to the "right" way.  After all that anguish, when the fateful day arrived that I had hooked the last splice and was ready to plug it in, it was nothing less than thrilling to have it take right off and work perfectly.  Done--and it only took 28 years!

The final touch was replacement of the cabinet, which had suffered at least one major tumble and was severely cracked at one corner, running along part of the top.  I'm very grateful to PrimeUser, who just happened to have the exact cabinet and donated it at no charge, thanks man!  *thumbs up*
